24p to 60i – best conversion method
I’m trying to convert some of our stock footage from 24p to 60i.
There is lots of information about the reverse 60i to 24p, but I’m struggling to get great results creating the opposite. I know for broadcast they do this for movies all the time, so there must be a better way.
My footage (to my knowledge) was shot on the RED one and 70mm, so it should be a true 24p ( with no pull down or segmented frames).
I’ve tried numerous methods of adding the 3:2 pull down in my render, but I haven’t found a solution that will work for our needs.
My main challenges are:
An increase in stutter (I expect due to the repeating of frames)
Edit pace increases due to higher frame rate.
With a 3:2 pull down, can I maintain audio synch?
I’ve also tried using pixel motion and Andrew Kramer’s frame rate converter, but haven’t found the solution that will work yet.
Any information about this is greatly appreciated.
Thanks,

they use telecine — just add a standard pulldown in the render settings and render with fields.
but as dave points out, if this is for distribution, most users will then need to remove the pulldown to get it back to 24p to use the footage.

Dave,
The content is already edited, and I’m trying to maintain the timing of the edit.
The content is specifically for a projector demo. The “flicker” associated with 24p won’t work for our presentation needs.
So I want to take the 24p stock, convert it to 60i for a 60i presentation.
In that process, I’m trying to maintain the pacing of the original edit and reduce the “stutter” effects of a 3:2 pull down.
I’m still not sure, does the 3:2 pull down maintain the timing of the original 24p content?
If not, how does the broadcast world deal with theatrical films that originated in 24p? -
Dave,
Thanks for the info.
Yes, flicker would be the generic term I was using for the appearance of moderately fast motion in 24p. Personally, I don’t mind the look, but the company decision is 60i. The thinking would be the use of interlaced frames would smooth out the 24p “flicker”.
I was hoping this would be a task I could do just with After Effects and/or Pixel Motion, but I will look into Magic Bullet and Twixtor.
Maximum frame rate for playback could be 60fps for both the playback and projector, but we would like to show the broadcast standard of 60i.
Thanks again,
Bart
